Oxford Semiconductor Launches World's First SATA to USB Bridge Chip for Next Generation External Storage
OXFORD, England—(BUSINESS WIRE)—Feb. 15, 2005—
A highly integrated device, the bridge chip dramatically
simplifies implementation of external hard disk and optical disk
drives for both PC and Mac platforms. In its 128-pin QFP package, the
OXU921S features an integral SATA Phy, USB2.0 Phy and ARM7TDMI
processor. The USB mass storage device firmware provided with the chip
ensures its full compatibility with standard operating system drivers.
The bridge chip's embedded USB2.0 Link and Phy support full and
high-speed modes and offer backwards compatibility with USB1.1. The
OXU921S has a 6kbyte cache for USB data, facilitating a data
transmission speed up to 480Mbit/sec. The integrated SATA core and Phy
operate at 1.5Ghz, resulting in a disk interface data rate of
150Mbytes/sec.
The use of a high-performance ARM7 processor, with 8Kbyte close
coupled RAM, means users are free to create highly differentiated
external SATA drive enclosures through custom firmware development. 12
GPIOs further extend the device's capability. An embedded UART is
provided for use in code development and debug and firmware can be
programmed through the USB port to help simplify manufacturing and
in-field updates.
To optimise the firmware development process, the OXU921S shares a
common software base with other Oxford Semiconductor devices and is
backed by a full development kit and evaluation board. The OXU921S is
available for sub 5.5 USD in 100K+ quantities.
